Comparison of the effect of platinum on producers in aquatic environment
Original language description
An enhanced worldwide application of platinum group elements (PGE), in particular platinum, has been observed during recent decades. An increased concentration of PGE was determined in collected samples of great amount of aqueous ecosystems.The aim was to compare phytotoxic effect of platinum (PtCl4) by performing two different bioassays on green algae Pseudokirchneriella subcapitata and macrophyte duckweed, Lemna minor. The algal experiment (Pseudokichneriella subcapitata) followed OECD 201, the concentration row for PtCl4 was: 0.05; 0.01; 0.25; 0.5; 1 ?M. The duckweed (Lemna minor) experiment was conducted according to OECD 221, employed PtCl4 concentrations were: 5; 10; 25; 50; 100 ?M. Plants were cultivated as a microbiotest, using micro-volumes. The results of the algal test showed significant growth inhibition of the final biomass. The values of 72hEC5(?), 72hEC10(?), 72hEC20(?) counted on a basis of average specific growth rate (?) were 0.31 ?M, 0.58 ?M and 1.12 ?M of PtCl4, res
